Protection of poor man's Majorana bound states in larger systems — •Viktor Svensson and Martin Leijnse — NanoLund and Solid State Physics, Lund University, Sweden

Majorana zero modes exhibit non-abelian properties that would be useful for quantum computation. In large systems the Majoranas can be well separated and thereby topologically protected, but this is difficult to realize experimentally. Small systems may be simpler to build, but as the Majoranas are closer together they are less robust. In a model with interacting quantum dots, we study how the protection of the Majorana bound states changes as the size of the system is varied.
